作为一个爱好骑行的博主，总觉得博客里少了点什么，骑行骑行的，怎么能没有一个专门的骑行数据展示页呢

在设计这个页面的时候，参考了许多骑行APP，然而，国内的骑行数据页面设计真的是一言难尽...

我骑行看数据用Strava多一些，但是它的PC端交互体验，实在不敢苟同。除了用APP版本，我几乎不会去它的网页。不得不说，国外这些骑行数据端做的确实很到位，我个人觉得数据分析方面Strava比Garmin要好！

## 项目结构

老规矩，先放目录结构。由于网站的主样式文件main压缩后都超160kb了，为了避免堵塞加载，新开辟一条生产线

说起SCSS，还是受Fooleap的启发才接触到的，我非常喜欢这种方式，它允许嵌套CSS，让代码更加模块化、结构化，还支持变量、继承。比起传统CSS那真是有过之而无不及啊！

## cycling.js
目前所有的逻辑都在这一个文件里完成，现在的功能还是个雏，因为没有打通Strava api，JSON数据是我手搓的..最近一直在搞Strava api，有好大哥懂吗？它们现在限制了每小时的请求次数，我本来就是半吊子水平，现在是雪上加霜
```js
import './cycling/cycling.scss';

let processedActivities = [];

## cycling.scss
骑行统计页面不会止步于此，接下来还会有很大的延申改动，我提前把变量接口留好了，定义了一些主样式变量，SCSS模块化继承了一些基础样式，二次开发会轻松很多
```scss
// 总次数和总距离字体
$primary-color: #2ea9df;
// 柱状图字体
$gray-color: #333;
// 柱状图颜色
$light-gray-color: #EBE6F2;
// 柱状图边框
$light-gray-border-color: #DFD7E9;
// 未活动日历
$no-activity-color: gray;
//------ 分类色
// 公路车
$cycling-color: #EBE6F2;
$cycling-border-color: #DFD7E9; 
// 跑步
$running-color: #D5E5D3;
$running-border-color: #BDD6BA;
// 背景和文本颜色
$background-color: #333;
$text-color: #fff;

@import 'base';
@import 'calendar';
@import 'bar-chart';
@import 'sports';
@import 'message-box';
```

## webpack配置
html和scss没啥好看的，配置一下收工
```js
const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const CssMinimizerPlugin = require('css-minimizer-webpack-plugin');
const TerserPlugin = require('terser-webpack-plugin');

module.exports = {
    mode: 'production',
    entry: {
        main: path.resolve(__dirname, 'src/main.js'),
        cycling: path.resolve(__dirname, 'src/cycling.js'),
    },
    output: {
        path: path.resolve(__dirname, 'assets'),
        filename: '[name].min.js',
        publicPath: '/'
    },
    stats: {
        entrypoints: false,
        children: false
    },
    module: {
        rules: [
            {
                test: /\.(scss|css)$/,
                use: [
                    MiniCssExtractPlugin.loader,
                    'css-loader',
                    'postcss-loader',
                    'sass-loader'
                ]
            },
            {
                test: /\.html$/,
                use: ['html-loader']
            }
        ],
    },
    resolve: {
        alias: {
            'iDisqus.css': 'disqus-php-api/dist/iDisqus.css',
        }
    },
    plugins: [
        new MiniCssExtractPlugin({
            filename: '[name].min.css'
        })
    ],
    optimization: {
        minimize: true,
        minimizer: [
            new TerserPlugin({
                parallel: true
            }),
            new CssMinimizerPlugin()
        ],
    }
};
```

## 效果
Fooleap的博客真的是相当不错，我特别喜欢他写的Jekyll主题，还有很大的折腾空间，比如全站PJAX、懒加载等等

这一周，我也着手用JQuery重新了写整站，完事后感觉真傻逼了，属于画蛇添足，多此一举。毕竟小站点，拖着一个磨盘挺累的。不上国内服务器的话，原生这条路死磕到底了，不过PJAX是必须要上的，预计下星期全站PJAX、懒加载上线
